In 1923, Wairarapa College was established and Masterton District High School became a primary school, renamed Masterton Central School.
In 1970, the school moved to South Rd and with the school mergers in 2004 was renamed Masterton Primary School.
Students had used a long rope to ring the bell when it sat atop the school building, although MPS pupils may still ring the bell at arm's length away at ground level, wearing ear muffs to dull the peal.
Mrs Brown said retired Masterton builder Merv Brown had been "the driving force" behind the revamp of the bell tower, which will be officially opened next week at a ceremony to which a number of dignitaries had been invited, including Masterton Mayor Lyn Patterson.
"Mervyn Brown was the driving force and there have been hundreds of hours, lots of materials, and lots of people and supporters involved in making this happen."
